SPECIFICATION forming part of Letters Patent No. 291,422, dated January1,1884,

' Application filed June 14, 1883. (No model.)

To all 1.0720771/ t may concern/.-

Be it knownthat I, HEINRICH S'rrnn, a

subject of the King of Saxony, residing at Zwickau, in the Kingdom ofSaxony and Empire of Germany, have invented new and useful Improvementsin Coke-Ovens, of which the following is a specification'.

The object of this invention is to secure a new arrangement in ovens orstoves, which is applicable as well for the preparation of coke as fordistillation, so that the heating of the` same is accomplished bygenerator-gases,

whereby, in case of interruption in the `operation, the generatorsarranged in front "of the coke-shafts may be thrown out and each`sepa-rate coke-shaft may be utilized as a generator.

. In the accompanying drawings, Figuresl to 4t show longitudinalsections. 2o

Fig. 7 is `a horizontalsection in the plane AB, Fig. 1. Fig. 8 is a plan view of aplant. Fig. 9` is a side view `ofthe same.` Fig. 10 is a cross-section in the plane@ D, Fig. 7, throughone of thegenera-tors lying in front of the coke-shafts; l

Similar letters indicate correspondin 0' parts. .The coke-shafts b Iare.surrounded by the heating-shafts b,.so as to isolate the former,an d thetwo are so formed that'\the vertical walls have horizontal openings,which in the case ofthe cokeshafts are so arranged that there is only anopening or connection at the top and the bottom, while, in the case ofthe heatingshafts surrounding the coke-shafts, such heatingshafts are soconnected Joy openings through their walls that thehcati 11g-gases maymove forward. l

"The drawings (Figs. 7 and 8) show a battery ot' six coke-ovens and fourgenerators, c a, surrounding the same, the plant being seen in plan viewand partly in section. 4Of course the number of parts may be variedaccording to desire and according to the quantity of material to beoperated on, it' only the rela- .7, which carries oft' the produc-ts ofcombus tion.

In front of each of the gas-generators is -a perforated stone wall orpassage, a?, which 1s arranged in the same manner as the perforated wallb7 in front of the coke-chambers, which will be hereinafter referred to,and which is shown in Fig. 4 in section. The same consists ofearthenware, stones, or bodies provided with horizontal passages goingentirely through them, and which are placed one upon the other in astep-shaped manner, so as to leave a passage for the air and to causethe air in passing to take a zigzag and regular motion through theperforated stone wall. The air required for the function of thegenerator is forced into the passage c2 through the openS `ing a', Fig.5, and passes from thence through the furnace c and to the generator a.The gases generated ,fin the latter pass. upon the opening of the slidesor registers a4 and at, Fig. 10, through the passage c, into-the passageormain-gas channel H G, Flgs. 2, 3, 6, and l0, provided for theirescape. Fromthese horizontal main gas-channels, which pass along ,underncath the entire ap parat-us, th egases p ass through the verticalopening b3, F1g. 7, into the heating-chambersb. about the coke-cham-Abers b. These heatinglchambers bf may be placed in communication withthe interior of the coke-chamber b by the slides or registers b2, Fig.main gas-channel H G, registers or slides b and b5, gas-channel b3,Figs. 2 and 6, and by the passage b, Figs. 2, 8, and 4, and perforatedstone wall b, constructed as .already set forth, and the passages ofwhlch wall are made to communicate by a ventilatingdome, bs, with theoutside atmosphere, Figs. 4 and 5. Also, the iire or heating chambers bcommunicate at their upper ends by registers b, Figs. 7 and 8, with themain exit- 4channel H V for the products of combustion, Figs. 7 and l0,through which the products of combustion may pass to the, chimney c,Fig. 7 A pipe or c ndu'it, b1", Figs. 5,6, and 8, is provided for c.rrying off by-prodnct-s and depositing them in a receptacle, bu,provided for them, which receptacle in, if desired, may

IOC

also be placed on top of the apparatus. The section L M and thelcft-handside of Fig.v G show a modified form of conduit bw.

The function ofthe apparatus is as follows: The heating or combustiblegases from the generators mingle at the openings b, Figs. 2, 3, and et,with the air entering through the perforated wall ci?, Fig. 4; then passthrough the fire or heating chambers b, about thecokechambers b andfinally reach the escape-channel H V, provided for the products ofcombustion, Figs. 6 and l0. rIhe vapors and products of distillationdeveloped in the interior of the cokechambers b pass off through openingbm, communicating with a tube, into the condenser and apparatus providedfor theirV reception, while in the continuation of the process thelighter non-condensible gases formed later on pass, upon theproperplacing of the slides or registers b b" b2b, into the main gaschannel HG, from whence they may again be utilized for heating the coke-chambersb, or for other purposes. If any disturbance occurs in the operation ofa generator, a, cach such generator can be thrown out by closing theair-inlet a, by any suitable valve which may be provided for thatpurpose, as also by closing the slides or registers a* and c, Fig. l0,to secure a double and secure closing. of the coke-chambers b is to beused as a generator, a slide or register in thetubedwis closed, theslides or registers b b'l b2, which lead to the main gas-channel H G,are opened, the

slide or register, which leads to the escapeA channel or chimney H V,for the products of combustion, is closed, and the bottom of thecoke-chamber b is opened to allow ashes and the like to fall out, and toallow air to pass through the glowing coke. If the bottom of thecoke-chamber is to remain closed, air may be allowed to enter throughatube or tubes, f, which,becomin g transformed into heatinggas, minglcswith that coming from the other generators, and may be used for theoperation of other coke-chambers. or for other purposes.

The non-condensible'gases resulting from the products of distillationare utilized,either alone or together with the gases generated in thegenerators a .or in the coke-chamber b, when worked as generators forthe heating of airheatcrs, blast-cupola, heating, puddling, lime, or'other technical furnaces, in such a manner that the conduit leading tothe respective furnaces is directly or indirectly in connection With theair -pump or forcing tube, which draws the respective gases from thecoke-shafts b. It' ahigher pressure of the gases is desired, a suitablemotor may be conveniently applied for this purpose. Should it be desiredto force i'n the air required for combustion, which now flows in throughthe opening a and the perforated wall a2, a system of tubes may bearranged on the roof of the furnace to utilize the radiating heat asthoroughly as possible, in

which case the ventilatorsdomes b8 would be If one replaced by slides,or regulators, or conical valves. In place of the perforated wall a?, asystem of tubes may also be employed.

The regular operation of the apparatus, as shown in the drawings, willbe readily understood. Ihe air for the generator cflows through theperforated wall al, where it becomes warmed, and is then transformed inthe generator a into heating or combustible gas, and iiows thence intothe heating shafts or chambers b', where it meets the air, which hasentered through a dome or ventilator, bs, through the perforated wallbl, where it is warmed, and through the passages b into theheating-chambers b. The result is that the combustible gases areconsumed in the heating-chambers b about the coke-shafts b, subjectingthem to intense heat. From the heating-chambers b the products ofcombustion pass, as already described, te the escape-channel H V, andthence they may be led directly out to the chimney. In case any onecoke-shaft, b, and its surrounding series of heating-chambers, b, is tobe thrown out of use for repairing or other purposes, it can be done bysimply closing the slide b". and theeasy accessibility from above andbelow allows each shaft or chamber by itself to be easily repaired.

XVhat I claim as new, and desire to secure by Letters Patent, is-

I. The combination, with a generator, a, and coke-shafts b, of channelsa2 and bl, arranged in front of and surrounding said generator andcoke-shafts, 'said channels being composed of layers of perforatedstone, or its described equivalent, for heating the gas or air used forcombustion, substantially as described.

2. In an oven adapted for the production of coke or distillates, thecombination, with agenerator, a, and coke-shaft b, of perforated Wallsat bl, constructed and arranged substantially as and for the purpose setforth.

3. The combination of the movable slides or registers a, c, b5, bl, andb2, with the entrance and exit channels of the coke-chambers, saidslides being arranged substantially as shown, whereby, by their properadjustment, each coke-chamber may be utilized as such, or by closing thepassage for the outiiowing products of distillation and connecting thecoke-chamber with the main gas-channel, each coke-chamber may beutilized as a generator, as set forth. A

4. rIhe combination, with the eseape-chan nel for the non-condensibleproducts of distillation, of a heating apparatus, consisting ofperforated walls or channels at' b7 in the surrounding or inclosingwalls of the generator and coke-shafts for the preliminaryheating of thegases, substantially as set forth.

In testimony whereof I have signed my name to this specication-in thepresence of two subscribing witnesses.
